SMILES OF A SUMMER NIGHT (Bergman, 1955)
classic bergman: a filmed play, actors as characters, sex, marriage, an early 20th century setting... and superhilarious situations (yeah he can be very funny)
it's almost like the 3 stooges, in a way, not in the sense of physical comedy but how stupidly people act. good times.
btw this was begman's first international success, it was shown at cannes without his knowledge, and after he made it nobody ever pestered him again and he was free to do what he wanted.
